Toyota delivered its first fuel cell vehicles on this day in 2002. Of the six Toyota Fuel Cell Hybrid Vehicles (FCHVs) produced, the Japanese leased four and two went to researchers at the University of California. Toyota originally began development of a fuel cell vehicle in 1992. These FCHVs produce only water vapor as an emission, as they are powered by generating electricity by combining hydrogen and oxygen. That electricity then powers the vehicle’s motors and charges its batteries. Toyota’s efforts resulted in a market ready production car, the Mirai, which went into production in December 2014 and is still offered today.
